TO ALL WHOM IT MAY CONCERN:

Be it known that I, -EZRAM JOHNSON, of Joliet, in the county of Will,and State of .Illinois, have invented a new and improvedWindow-SashFastcnenand Lock; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in which-Figure 3is a detail vertical section of the sash taken through the linez z, fig. 4, and showing the mode of operating the fastener.

Figure 4 is a detail vertical section of'the same taken through the lineI z, fig. 3.

Similar letters of reference indicate like parts'.

My invention has for its object to furnish 'an improved window-sashfastener and lock, soconstructed and arranged that it will hold the sashat any desired elevation, and when the sash is closed, will hold itsecurely locked; and it consists in the combination of a toothed wheeland sliding ratchet-bar with the camshaft of the fastener, ashereinafter more fully described.

A is the sash, and B the casing of a window, about the construction andarrangement of which parts-there is nothing new. In the groove of thecasing B, in which the sash A slides up and down, is formeda recess intowhich is fitted the 'case C of the-fastener, as shown in fig. 4. D istlie cam or fastener, the shaft of which works inbearings formed in thesides of the case or cap C, as shown in fig. 4. The face of the cam Distoothed, as shown in the drawings, so that it maytake hold of the sashA, and hold it securely at any elevation to which it may have been'raised. The teeth of the cam D should be made of such a form that they willallow the sash to be raised, but will prevent its being lowered untilthe cam is moved away therefrom. The cam D is so formedthat it is heldforward against the sash A by its own weight, and it can only he movedaway to allow the said sash to be lowered by operating the shaft E. Whenthe sash is entirely closed or lowered the cam D drops, by its ownweight, into the notch a formed in the edge of the sash A, and locks insecurely. The shaft E may be made in one piece, or, i-ifldesired, it mayhe made in two parts or pieces, a" and e, the inner end of the part ebeing made square and fitting into a square socket formed in the end ofthe part e When the walls of the building are thick, and consequentlythe distance fromvthe earn D to the inner sideb of the casingconsiderable, the shaft E need not extend clear through, but may have atoothed wheel or a-segment of a toothed wheel, 1F, attached to its end,within a recess, 6 formed within ithe'casing B for thatpurpos'e. In thiscase the wheel F is operated, and through it the cam D, by aratchet-rack or toothed har,..G-, working in a groove formed for it inthe casing 13, as shown in fi'g. 3

I claim as new, and desire to secure by Letters Patent- The toothedwheel F, in the recess 6 of the casing '13, attached to the end of theshaft E, cam D, and toothed bar G,.when constructed, arranged, andoperating as herein set forth for the purpose specified.

The above specification of my invention signed by me this 30th day ofJuly, 1866.
